Hadoop 纱 : Get a list of available queues

Question

有没有办法从命令行获取所有可用 YARN 队列的列表，而无需解析 capacity-scheduler.xml 文件？

Answer 1

您可以使用 hadoop 内置的 mapred 命令行工具

me@here.com$ mapred queue -list
======================
Queue Name : root.tenant1
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
    ======================
    Queue Name : root.tenant1.default
    Queue State : running
    Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
    ======================
    Queue Name : root.tenant1.users
    Queue State : running
    Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================
Queue Name : root.tenant2
Queue State : running
Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
    ======================
    Queue Name : root.tenant2.default
    Queue State : running
    Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
    ======================
    Queue Name : root.tenant2.users
    Queue State : running
    Scheduling Info : Capacity: 0.0, MaximumCapacity: UNDEFINED, CurrentCapacity: 0.0
======================

它提供了一个简单而漂亮的层次结构输出
